What is the molecular shape of BF3?

Chemistry
2 answers:
mr_godi [17]3 years ago
8 0

Answer: molecular shape of BF_3 is trigonal planar.

Explanation: Formula used

:{\text{Number of electrons}} =\frac{1}{2}[V+N-C+A]

where, V = number of valence electrons present in central atom i.e. boron = 3

N = number of monovalent atoms bonded to central atom=3

C = charge of cation = 0

A = charge of anion = 0

BF_3:

{\text{Number of electrons}} =\frac{1}{2}[3+3-0+0]=3

The number of electrons is 3 that means the hybridization will be sp^2 and the electronic geometry of the molecule will be trigonal planar.

If an M&amp;M weighs 0.88 grams, how much would a mole of M&amp;Ms<br> weigh?
Snezhnost [94]

Answer:

5.30x10²³g

Explanation:

A mole can be understood as an amount of something.

One mole of eggs are 6.022x10²³ eggs

One mole of atoms are 6.022x10²³ atoms

One mole of molecules are 6.022x10²³ molecules

And 1 mole of M&M are 6.022x10²³ M&M. As 1 M&M weighs 0.88g, 1 mole will weigh:

0.88g*6.022x10²³ =

<h3>5.30x10²³g</h3>

Calculate the final temperature of the system: A 50.0 gram sample of water initially at 100 °C and a 100 gram sample initially a
katrin2010 [14]

Answer:

The final temperature of the system is 42.46°C.

Explanation:

In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.

q_1=-q_2

m_1\times c\times (T_f-T_1)=-(m_2\times c\times (T_f-T_2))

where,

c = specific heat of water= 4.18J/g^oC

m_1 = mass of water sample with 100 °C= 50.0 g

m_2 = mass of water sample with 13.7 °C= 100.0 g

T_f = final temperature of system

T_1 = initial temperature of 50 g of water sample= 100^oC

T_2 = initial temperature of 100 g of water =13.7^oC

Now put all the given values in the given formula, we get

50.0 g\times 4.184 J/g^oC\times (T_f-100^oC)=-(100 g\times 4.184 J/g^oC\times (T_f-13.7^oC))

T_f=42.46^oC

The final temperature of the system is 42.46°C.
